As an industry leader, fire pump Manufacturer designs and manufactures an extensive range of high-performance pumps specifically designed for firefighting applications. Their focus on cutting-edge technology, reliability, energy efficiency, durability, and global support positions them as a top choice among customers looking to purchase fire pump systems.
The first step in selecting a fire pump is identifying the flow and pressure boost required for your building. Once this information is known, a fire pump can be evaluated for suitability using the manufacturer’s performance curve. This graph plots the flow of the fire pump (typically on the “x” axis) against the net pressure produced by the pump at each flow condition between churn and maximum flow. Ideally, the net pressure is lower than the maximum rated flow.
During the performance test, the pressure gauges and transducers used to measure the flow and pressure must be of extremely precise quality. If these instruments are not calibrated to the manufacturer’s specifications, then they must be replaced. This is important because the pressure and flow readings must be accurate for the fire pump to pass the NFPA 25 flow test.
Once the performance curve has been analyzed, it must be compared to the rated pressure of the downstream fire protection system components. The fire pump must be sized correctly so that its power output is greater than the pressure of the downstream fire protection system components. If a fire pump does not meet this requirement, it may not be suitable for the fire protection system design and will need to be replaced.
